Welcome! I am an Associate Professor at the Department of Mathematics and Statistics, Boston University. I am also affiliated with the Center for Information and Systems Engineering, Boston University
and I am a junior faculty fellow at the Hariri Institute at Boston University. I completed my PhD at the
Department of Mathematics, University of Maryland at College Park, advised by Professor Mark Freidlin and I was at
the Division of Applied Mathematics, Brown University
as a Prager Assistant Professor from 2009-2012.
My undergraduate studies were in Applied Mathematics and Physics at the National Technical University of Athens in Greece.
(NTUA).
Research interests:
My research lies broadly in the areas of stochastic processes, statistical learning, applied mathematics and probability,
large deviations, multiscale methods, financial mathematics,
asymptotic problems for stochastic processes and partial differential equations ,
statistical inference for stochastic differential equations. In particular:
- Mathematical and computational methods for machine learning algorithms
- Stochastic optimal control and optimization
- Monte Carlo methods and development of rare event simulation methods
- Asymptotic problems for stochastic processes and partial differential equations (PDE's) such as multiple scale problems and large deviations
- Metastability analysis of dynamical systems
- Systemic risk and risk managenemt, large portfolio asymptotics, stochastic volatility models and large deviations
- Statistical inference for stochastic differential equations
